Hey ! try to think about the case when left column and right column becomes equal. i.e. for the test case 4 3
11 12 13
21 22 23
31 32 33
41 42 43
ur code is printing wring output. before printing buttom to top you should first check wheather this line is printed before or not that is if left and right are equal then this line was already printed before.
